Comparative study of intraperitoneal adhesions related to light-weight polypropylene mesh and type I polymerized and purified bovine collagen coated light-weight polypropylene mesh in rabbits 1 2-Experimental SurgeryActa Cir Bras. 2017;32(11):903-912 AbstractPurpose: To compare the effectiveness of light-weight polypropylene mesh coated with polymerized and purified bovine type I collagen (Surgidry HNB) in the treatment of abdominal wall defect and the degree of adhesion formation. Methods: Two types of polypropylene mesh were implanted after creation of defect measuring 6.0cm X 5.5cm in the anterior abdominal wall of 32 male New Zealand breed rabbits, divided in two groups (n = 32): (1) light-weigh macroporous polypropylene, (2) type I polymerized and purified bovine collagen coated light-weigh macroporous polypropylene. These animals were further accessed for adhesions, histological evaluation of inflammation and wall's thickness. Results:The percentage of the area adhered in group 1 (62.31 ± 16.6) was higher compared to group 2 (22.19 ± 14.57) (p <0.05). There was an association between the percentage of the covered area by adhesions and the type of adhesion, toughness and the scores obtained by the adhesion score by correlation analysis (p <0.05). There was no difference between the groups in any variables in relation to the degree of inflammation. Conclusion:The purified type I bovine collagen coated light-weigh polypropylene mesh showed to be effective in the repair of abdominal wall defects and reducing adhesion formation. 903Comparative study of intraperitoneal adhesions related to light-weight polypropylene mesh and type I polymerized and purified bovine collagen coated light-weight polypropylene mesh in rabbits Garcia DPC et al.

A ritidoplastia, ou cirurgia do rejuvenescimento facial, tem se tornado uma das cirurgias plásticas estéticas mais procuradas em todo o mundo e, como qualquer outra cirurgia, apresenta riscos de complicações. O hematoma pós-operatorio, a complicação mais comum, tende a se apresentar precocemente, mas em alguns casos ocorrem dias após o procedimento. Podem ocorrer de forma leve, com pequenas coleções, ou podem se desenvolver com sangramentos ativos volumosos, classificados como hematomas expansivos. Apresentamos o caso de uma paciente submetida à ritidoplastia completa, evoluindo tardiamente com hematoma cervicofacial levando a instabilidade hemodinâmica e comprometimento de via aérea.

IntroductionIntestinal obstruction is the second among the most frequent acute abdominal conditions of the non-traumatic surgical pathologies. It is Found in 20% of patients admitted to the emergency care services with acute abdominal pain. It often results in high morbidity and mortality.Presentation of caseWe report a case of a foreign body resulting in a colon obstruction, concomitant with the diagnosis of a sigmoid cancer in a 47-year-old female.DiscussionThere are only a few cases of Intestinal Obstruction Induced by Peach Stone in Stenosis of Sigmoid Colon by Adenocarcinoma reported in the world literature. Due to late diagnosis It has a high mortality rate. Vomiting and emesis, abdominal distention, dysphagia, colicky abdominal pain, failure to pass flatus and anorexia are clinical findings. The immediate treatment is importance for patient survival.ConclusionIntestinal obstructions and perforations are rare conditions caused by the ingestion of foreign bodies. These conditions must be taken into consideration especially owing to differing diagnoses and previous pathologies concomitant with the ingestion of objects such as those described in the foregoing adenocarcinoma case.
